https://github.com/openshift/cluster-dns-operator/pull/373 introduced some typos on DNS condition messages or reasons by adding a space after strings.Join conjuctions. To make progress on this PR, we decided to overlook the typos and follow up in this bug.

For example,

messages = append(messages, strings.Join(upgradingMessages, "And "))

progressingCondition.Reason = strings.Join(progressingReasons, "And ")

availableCondition.Reason = strings.Join(unavailableReasons, " ")
